摘要：
The synthesis used urea and Zr(NO3)(4)center dot 5H(2)O as material to prepare tetragonal-ZrO2 nanocrystals through microwave-induced combustion process. The tetragonal-ZrO2 nanocrystals were characterized by X-ray diffraction (XRD). The effect of Zr4+/urea molar ratio on the synthesis of tetragonal-ZrO2 were studied. It was found that tetragonal-ZrO2 crystal would be better when the Zr4+/urea molar ratio was larger than 1:3. The SEM images of the samples showed the hollow structures formed at different levels of molar ratio of Zr4+/urea. This method is a simple but effective route to prepare tetragonal-ZrO2 nanocrystals.
